How much did CR spend to buy these spices? A few hundred dollars? A thousand at most? I don't know how much the tests themselves cost to run, but I can find lead test kits on Amazon for under $20. The biggest cost would doubtlessly be manpower so.. put some interns on the job?
But yes, I expect the FDA's lame excuse will be "Gee wiz we wish we could do our jobs but we need another billion dollars for what you're suggesting." Such is the way with the American government.
